From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7) Gecko/20040803 Firefox/0.9.3 Description of problem: Just After a fresh install from Fedora Core 2 CD's, evolution and other mailers are working fine. But as the uptodate applet warns me that a huge set of updates are available I updated my system with yum (yum update). It's where the problems are appearing. When I start evolution and click on [Send/Receive] button the 'Send & Receive Mail' dialog pops up and hangs in the waiting state for the pop server. When I click on the [Cancel] button of the dialog, a new dialog 'Enter Password for myUsername@swing.be' prompts me for my password and displays the message 'Unable to connect to POP server pop.swing.be. Error sending password: Unknown error' The last dialog endlessly comes back with the same error message each time I click on the [OK] button. The same behaviour appeared when I tried other mailers (mozilla-mailer -1.7.2-0.2.0 and thunderbird-0.7.3) : they both hang when connecting to the pop server. Version-Release number of selected component (if applicable): evolution-1.4.6-2 How reproducible: Always Steps to Reproduce: 1. launch evolution from the Gnome Panel 2. click on the [Send/Receive] button 3. here is the bug; the mailer hangs Expected Results: sucessful connection to POP server (obviously) Additional info:

As you can see in the attached log file there is a problem with the dns related packets (bad udp cksum). The problem occurs while running the 2.6.7 kernel version. I solved the problem by opening the firewall for udp port 53 and retricted the allowed sender ip to my ISP's dns servers. Then I rebooted with kernel 2.6.5. All works fine. I can now say that the problem is related to the 2.6.7 version of the kernel but don't know exactly where the problem is.
Fedora Core 2 is now maintained by the Fedora Legacy project for security updates only. If this problem is a security issue, please reopen and reassign to the Fedora Legacy product. If it is not a security issue and hasn't been resolved in the current FC3 updates or in the FC4 test release, reopen and change the version to match.
Closing per lack of response. Also note that FC1 and FC2 are no longer supported even by Fedora Legacy. If this still occurs on FC3 or FC4, please assign to that version and Fedora Legacy. If it still occurs on FC5 or FC6, please reopen and assign to the correct version.
